HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 501,974, dated July 25,1893. Application filed May 11, 1892. Serial No. 432,629- (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM VANDERMAN, of Willimantic, in the county ofWVindham and State of Connecticut, have invented certain new and usefulImprovements in Hot- Water Heaters, of which the following is a full,clear, and exact description, whereby any one skilled in the art canmake and use the same.

The object of my invention is to provide a combined boiler and furnacethat is more particularly adapted for providing hot water to be used forheating dwelling houses and public buildings, and one in which therewill be secured a uniformity of heat with economy of fuel.

To this end my invention consists in the details of the several partsmaking up the hot water heater as a whole and in their combination asmore particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure 1 is a detail view in vertical sectionthrough the heater the line of section passing through the connectingwater fiues. Fig. 2 is a detail view in vertical section through theheater on a plane at right angles to the plane of view of Fig. 1. Fig. 3is a detail plan view of one of the boiler sections. Fig. 4 is a detailplan view of one of the upper boiler sections.

My improved apparatus comprises a furnace and a boiler made inhorizontal sections that are secured together as by means of bolts andprovided with fiues for the circulation of flame, and gases ofcombustion and with other flues for the circulation-of the water throughthe boiler parts.

In the accompanying drawings the letter a denotes the base of the boilerand furnace made preferably hollow so as to form an ash pit and open atthe top for the reception of a grate a. On this base the boiler issupported, the lower section b containing the fire pot 1). Above thisare arranged the sections 0, d, e and f that are secured together bymeans of bolts passing through the flanges that project from the top andbottom edges of the sections. The second section 0 has a re-entrantbottom 0 forming a heating drum that directly overlies the combustionchamber and into which the heated products of combustion rise directfrom the mass of burning fuel in the fire pot. The bottom of thissection 0 forms the crown sheet of the boiler. the section d is recessedso as to form a deflector chamber (1 and the lower surface of the uppersection f has also a likedeflector chamber f. Through each of thesections above the bottom section, flues g are formed near the outeredge of the boiler and they register with each other so as to form acontinuous flue from the combustion chamber to the deflector chamberf',and'the products of combustion rise directly through these flues. Acentral fine 1' extends from the deflector chamber d through thesuperimposed sections and connects directly with thesmoke stack orchimney. In case a direct draft is desired a damper i in the side ofthis central flue is opened and this gives a direct outlet from thischamberf' and of course from the flues communicating therewith. A secondseries of tubes extend between the two deflector chambers d and f andwhen the damper t" is closed an indirect draft is created, the flamesrising through the flues g descending through the tubes 9 and thenrising through the central flue 2'. By this construction of parts thewater surrounding these flues in the several sections is thoroughlyheated and a large percent. of the heat caused by the combustion of thefuel is utilized.

Connections are made for the usual flow pipes it from the upper part ofthe water chamber of the boiler and a return connection Z is made withthe water chamber of the boiler near its bottom.

A handle not shown for operating the damper z" extends through the wallsof the section and is arranged on the outer side of the furnace in aconvenient position to enable the damper to be moved.

The water chambers of the several sections are connected by means ofwater ways at that are formed in the cylindrical projections pref erablyformed in any desirable number on the peripheries of the boilersections, and so located on each section as to overlie one another whenthe sections are bolted together and form a continuous water way. Thewater space within each section, of course, communicates freely with thevertical water ways by having the side of the tubular way open. Theresult of this construction is that a free The under side of flow ofwater is established from the lower sections through each of theintermediate sections to the upper end of the boiler and out ihrough theflow pipes to the pipes of circulaion.

As already explained a thorough contact of the water with the heatedsurfaces is provided for by the construction of the several fluesproviding for the indirect movement of the flames and heated gases ofcombustion through the uptake.

I claim as my invention 1. In combination in a sectional boiler andfurnace the lower section forming the firepot, an upper section 0 havinga number of vertical flues located near the sides of the fire-pot andhaving a re-ent'rant bottom forming a chamber extending above the flueoutlets, all substantially as described.

I11 combination in a sectional boiler and furnace the lower sectionforming a fire-pot, the sections overlying the fire-pot, a series ofvertical fiues extending from the fire-pot to a deflector chamber. inone of the upper sections, a series of inner flues extending from theupper deflector chamber to a lower deflector chamber in one of theintermediate sections, and a central flue extending upward from thelower deflector chamber, all substantially as described.

3. In combination in a sectional boiler an furnace the lower sectioncomprising the firepot, an upper section having a re-entrant bot tomforming a combustion chamber, a deflector chamber located below thebottom section, the Vertical flues extending from the fire-pot to thedeflector chamber, a central flue extending through the upper sectionsof the boiler and a damper located in the side of said flue andcommunicating between the upper deflector chamber and a central flue,all substantially as described.

4. In combination in a sectional boiler and furnace the lower sectioncomprising the firepot, the crown sheet section having a re-cntrantbottom forming a combustion chamber, a deflectorchamber located belowthe dome section of the boiler, a lower deflector chamber locatedbetween intermediate sections of the boiler, vertical flues extendingfrom the fire pot to the upper deflector chamber and from theupperdeflector chamber to the lower and a central smoke flue extendingfrom the lower deflector chamber through the upper sections of theboiler, and the damper located in the side of the central flue andcommunieating with the upper deflector chamber with a handle extendingto the outside of the furnace, all substantially as described.

5. In combination in a sectional boiler and furnace, the lower sectioncomprising the firepot, the upper sections overlying the fire pot, adeflector chamber located below the dome section, a deflector chamberlocated between the intermediate boiler sections, a series of fluesextending from the fire-pot to the upper deflecting chamber, an innerseries of tubes extending between the deflector chambers, a centralsmoke flue extending from the lower deflector chamber, and thewater-ways extending between the several sections and coinmunicatingwith the water chambers therein, all substantially as described.
